IMPROVEMENT IN TOBACCO-PIPES.

Specification forming part of Letters Patent N o. l91,35, dated May 29,1877; application tiled March 12, 1877.

To all whom 'it may concern Be it known that I, SAMUEL H. THURsroN, of Whitestone, in the county of Queens and .State of New York, have invented a Demand@ useful Improvement in Tohacco-.Pipesand OigarHolders, of Wliichrtheltollowing is a specication: y,

Figu-rel is a side elevation, in section, of a. tobacco-pipe containing my improvement.

Y Fig. 2 is a longitudinal section on line x x, "L'Fg, 3. Fig. 3 is a plan view ot' a pipe-bowl made of pumice-stone. Fig. 4 is a longitudinal section ot' a cigar-holder having a lining' of pumice-stone. Fig. 5 is a longitudinal section of a cigar-holder made of pumice-stone, and provided with a mouth-piece of other material. Fig. 6 is a longitudinal section, and Fig.

7 is a transverse section ot` a pipe-stem lined with pumice-stone.

Similar letters ot' reference indicate corresponding parts.

My invention relates to improvements in pipes for smoking tobacco; and it consists in making the entire pipe or portions thereof, or a cigar-holder or portions thereof, of pumicestone.

The requisite qualities for a good pipe or cigar-holder are lightness, porosity, and' indestructibility. Hitherto only the most eXpen sive kinds of pipes have possessed some of these qualities in a limited degree. To produce au inexpensive pipe having all these features is the object ot' my invention.

Referring to the drawing, A, Fig. 1, is the bowl of any ordinary pipe, in which isplaced a lining ot' pumice-stone, consisting ot a cylindrical part, B, and a perforated bottom piece, C; or the cylindrical part and bottom may consist of a single piece.

In Figs. 2 and 3 a pipe-bowl is represented that is formed from a block of pnmieestone, and is designed to be used in connection with any ordinary stem.

A1, in Fig. 4, is/a'ci r-holder, of any suitable mater/ialaaiorm, in which is placed a pumicefs'tne h ing, B1, which receives the fiend ot' the ciga A2, in Fig. 5, is a stem ot' any suitable material, to which is attached a holder, B2, which is made from pulnice-stone.

In Figs. 6 and 7, A3 is a pipe-stem, which is provided throughout the whole or a portion of its length with a pumice-stone lining, B3.

These various examples represent the princi. pal forms of my invention, the object of which is to provide a pipe shaped from pumice-stone in its natural state, and to provide linings to such portions as are subjected to heat, and With which nlcptineadidotlmr liquid products oil-the combustion of tobacco Ycome into contact as the smoke is drawn from the pipe.

The pumice-stone, being porous, absorbs the liquid products of combustion, and, being refractory, resists the action oi' the heat. It is also very light, and may be cleansed by heat- -ing or by treating' with alcohol or acids, and is practically indestructible. i

Instead of pumice-stone in its natural state, it may be pulverized and mixed with some cementitious material t'or the manufacture of pipes, cigar-holders, or linings; but the porosity ot' the natural' stone Would thereby be almost entirely destroyed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A pipe-bowl or cigar-holder formed from pumice-stone, substantially as herein shown and described.

2. The combination, with the bowl or stem of a cigarholder or pipe, ot' a lining of pumice-stone, substantially as herein shown and described.
